Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, especially in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of bioactive compounds and functional materials. The phenolic hydroxyl group allows for further derivatization, enhancing its utility in multi-step syntheses. Commonly employed in the preparation of diaryl or aryl-heteroaryl structures found in drug candidates and advanced intermediates.
